Programme to monitor gains/losses in a zero-energy house with PV and HVAC?

Welcome.
We are looking for a program, a package that will make it easier for us to "pin down" a system that monitors gains and losses in a model home and show this online.
Specifically:
Assumptions:
- a demonstration house where we want to put some data on the internet available online for internauts
- room temperature sensors - 5 pcs.
- humidity sensors - 2 pcs.
- temperature sensor in the mechanical ventilation system:
- on the air intake
- on the outlet
- on the supply air
- on the exhaust
- recuperator efficiency
- amount of electricity consumption in underfloor heating system (electric heating)
- amount of energy produced from photovoltaic panels

Thank you for your help and reply

And airflow meters on the recuperator would also be useful, so as not to deceive people with super efficiency. Related to the topic, you need a PLC + panel. Data from some panels can be presented on the web. There are really many solutions. It all depends on the hardware. And first of all it depends on your budget.

When you write flow meters - do you mean capacity?
If so, I rather don't see a sensible solution here....
As for the costs: we would first have to know the difference between the different solutions, then we can decide which solution will be the most advantageous for us.

PLC:
controller: Fatek e.g. Fbs-20MAJ2-AC -600 PLN (net)
communication: FBs-CBE module (Ethernet) - 320,-
temperature measurements: FBs-RTD16 module (16 RTD inputs) - 1200,-
current measurements: FBs-6AD module (6 analogue inputs, 14 bits) -620,-
NOTE: the number of inputs is "oversized";
for this Falcon Server (free) - a PC program that communicates with the PLC and downloads data.
Then the data as DDE can be sucked into excell and other applications.
